Flutter 不是为 1.10 或更高版本构建的

Question

最近我更新了我的flutter版本，然后我得到以下错误：

Launching lib/main.dart on Android SDK built for x86 in debug mode...
Running Gradle task 'assembleDebug'...
Warning: Failed to parse host [PROXY SERVER] systemProp.http.proxyPort=[PROXY PORT]
Warning: Failed to parse host [PROXY SERVER] systemProp.http.proxyPort=[PROXY PORT]

FAILURE: Build failed with an exception.

当我创建一个新项目时，它也会产生这个错误。我尝试了不同版本的 flutter，1.9.7 版本有效。更高版本创建所有相同的错误。 gradle 好像有问题。使用 gradle 3.2.1 一切正常。

我认为这与您在前 5 行的警告中指出的代理配置有关。

检查您在 gradle.properties

中的代理配置

Flutter 不是为 1.10 或更高版本构建的

Flutter not building for version 1.10 or higher

android

gradle

android-gradle-plugin

flutter
